CARBURETOR.

GPEC'IFICATION forming part of Letters Patent No. 303,927, dated August19, 1884.

Application filed January 16, i884. (No model.) I

To (455 whom. it M21111] concern:

Be it known that I, GEORGE FRoH, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful lmprovement in Carburetors, whichimprovement is fully set forth in the following specification andaccompanying drawings,in which- Figures 1 and 2 are vertical sectionsatright angles to each other ofa carburetor embodying my invention. Fig.3 is a horizontal section on a reduced scale in line a: m, Fig. 2.

Similar letters of 'reference indicate corresponding parts in theseveral figures.-

My invention consists of a carburetor in which the flow of thecarbui'eting-fluid is automatically and nicely controlled in twochamhers, and other details of construction are presented, as will behereinafter fully set forth.

Referring to the drawings, A represents a casing made of any suitablematerial, preferably metal, the same being divided into areceiving-chamber, B, a chamber, 0, communicating therewith, with aperforated or gauze partition, 0, between them, a floatand valvechamber, D, another float-chamber, E, a carbureting-chamber, F, and adrip-receptacle,G.

Secured to the bottom of the chamber 0 is a hollow valve-seat, H, thesame having openings or ducts a, which open into said chamber 0, thebottom of said seat opening into the chamber D, thus forming acommunication between the chambers C D.

J represents a valve, which opens downwardly from said seat H, and issecured to the stem J, which is properly guided in the scat H and thebottom of the chamber D.

Loosely encircling the stem J, below the valve J in the chamber D, is asleeve,K,which is attached by means of a bar, K, to floats L in the samechamber D; and firmly secured to said stem J, between the valve J andsleeve K, is a stop and deflector, M.

Communicating with the chambers D and F is a pipe, N, which in thechamber F is formed with perforated branches N", from which aresuspended strips or pieces P of ab sorbent material, the same beingadapted to be saturated by hydrocarbon fluid which escapes through theperforations of the branches N.

At the bottom of the stem J is a float, Q,

position within the chamair-discharge pipe leading from said chamber,

it being noticed that said chamber is threesided and thereby enlarged.

T represents a pipe communicating with the chamber G for discharging thedrip and accumulations of said chamber.

The operation is as follows Gasoline or other hydrocarbon fluid isadmitted into the chamber B through the supply-pipe U, and the displacedair escapes through the pipe V. The fluid enters the chamber 0, andflows into the valveseat through the ducts a, and enters the chamber 1),whence it is directed by the pipe N and branches N into thecarburetingchamber F, saturating the material P, as has been stated. Airis forced through the pipe B into the chamber F and passing through thesame, and the saturated material 1? becomes charged with hydrocarbon andcarburetcd, in which condition it is discharged through the pipe S anddirected to the place of service. Should the fluid flow too freely fromthe chamber (J and collect to an undesirable extent in the chamber D,the floats L rise and cause the sleeve K to strike the stop M, wherebythe valve J is raised and accordingly closed. Vhen the supply of fluidis equalized or adjusted, the floats fall and permit the valve toreopen. Should there be a collection of fluid in the chamber F, it mayescape therefrom through an'opening, W, in the inner vertical wall ofthe chamber E into said chamber E, and cause the float Q to rise andclose the valve until said collection is dis posed of either byevaporation or escape into the chamber G through an opening, X, at thebottom of the chamber E, said opening also permitting water, condensedmatters, and drip generally to enter the chamber G, from which the samemay be pumped or otherwise re moved by the pipe T, as has been hereinbefore referred to.

In order to cause the floats L Q to movesteadilyandwithfacility,thesameareprovided with rollers, which areproperly guided within the chambers containing said floats.

Y represents wood or other proper material with which the casing Aislined, thus protecting the interior of the carburetor from theinfluences of changes of temperature and other injurious effects.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A carburetor having a valve, a float in the chamber leading to thecarbureting-chambar, and a float in the chamber leading from saidchamber, both floats closing said valve when there is an excess ofcarbureting-fluid. in either chamber, substantially as and for thepurpose set forth.

2. The floats L Q in different carburetingchambers, in combination withthe valve J,the
